What is Network Time Protocol (NTP) in networking?
Networking , Technology & Science / June 7, 2018

Network Time Protocol (NTP) is very important for modern networks. If the time across network devices is not accurate, this can have a direct impact on network security and network management, just to name two. The key to accurate time in the network is to have your devices receive the correct time from an atomic clock, and then synchronize this correct time across all of the devices. Network Time Protocol ensures this process is aut...
